A beekeeper found that when stung by a bee, application of a little solution of sodium hydrogen carbonate helped to relieve the irritation of the affected area.Explain
Answer:
A bee sting releases an acid. When sodium hydrogen carbonate is applied, it neutralizes the acid since it's a base.
Explanation:
The sting of an bee contains formic acid. When an bee stings, it injects the acidic liquid into the skin, similar to ants. The effect of the sting can be neutralised by rubbing moist baking soda (sodium hydrogen carbonate) or calamine solution, which contains zinc carbonate.
Sodium hydrogen carbonate neutralizes the acid present in a bee's sting.
Explanation:
When we get stung by a bee, it releases a formic acid which irritates the affected area.And in order to relieve the irritation, we neutralize the formic acid by using sodium hydrogen carbonate which is basic in nature.Sodium hydrogen carbonate is basic in nature reacts with formic acid present in the sting to relieve the pain or irritation on the skin.The reaction between sodium hydrogen carbonate and formic acid occurs to give sodium formate, water, and carbon dioxide as a product[tex]NaHCO_3+HCOOH\rightarrow HCOONa+H_2O+CO_2[/tex]

Why do our liver cells contain so many smooth ER?
Answer:
Liver cells contain lots of smooth endoplasmic reticulum because the liver plays a big role in detoxification. So, if you've had a few too many glasses of wine, it's the smooth endoplasmic reticulum in your liver that's helping move things along the next morning

I need help with 5 and 6!!
Answer:
As the axial tilt increases, then the seasonal contrast increases so that winters are colder and summers are warmer in both hemispheres. The northern hemisphere is tipped away from the Sun, producing short days and a low sun angle. What kind of effect does the earth's tilt and subsequent seasons have on our length of daylight (defined as sunrise to sunset). Over the equator, the answer is not much.
As for #5, it's mixed at the end of my answer, but just remember the spring equinox marks the change from 24 hours of darkness to 24 hours of daylight at Earth's poles .

How does the velocity of a falling object change over time?
The Earth is thought to have been formed about 4.6 billion years ago by collisions in the giant disc-shaped cloud of material that also formed the Sun. Gravity slowly gathered this gas and dust together into clumps that became asteroids and small early planets called ___.
Answer: dwarf planets
Explanation:
Answer:
planetesimals
Explanation:
these are the building blocks of planets, sometimes called "planetesimals." Scientists think planets, including the ones in our solar system, likely start off as grains of dust smaller than the width of a human hair. They emerge from the giant, donut-shaped disk of gas and dust that circles young stars.

Is copper II chloride mixed with water an element, compound, or mixture? If it's a mixture is it homogeneous or heterogeneous?
Answer:
1. mixture
2. Homogenous
Explanation:
Copper II chloride is a compound because it consists of elements that are chemically combined together. When a solute in this case, copper II chloride is mixed with water- a solvent, the result is a homogenous mixture.
Homogenous substances are formed when a solute and a solvent combine, resulting in a mixture with uniform properties. Mixtures can be separated using relevant separation techniques.

Explanation:
Typically, your percent yield is ______ than 100% because ___________________________.
Reasons why percent yield is more than 100
Typically, percent yields are understandably less than 100% because of the reasons indicated earlier. However, percent yields greater than 100% are possible if the measured product of the reaction contains impurities that cause its mass to be greater than it actually would be if the product was pure.

Which of these is evidence that an unbalanced force is acting on an object?
The motion of the object is changing
The mass of the object is changing.
The object continues moving in a straight line
The object remains at rest.
Answer:
The motion of the object is changing
Explanation:
Objects will only change their motion (direction, speed) if there is an unbalanced force of some kind acting on them. Balanced forces result in no change in the object's state of motion.
The motion of the object is changing.
Objects will only change their motion (direction, speed) if there is an unbalanced force of some kind acting on them. Balanced forces result in no change in the object's state of motion.
What is motion ?
"Change with time of the position or orientation of a body. Motion along a line or a curve is called translation. Motion that changes the orientation of a body is called rotation."
What is force ?"A force is a push or pull upon an object resulting from the object's interaction with another object."

What happens to that atom of magnesium-24 if it GAINS a NEUTRON? *
Answer: If this atom loses one electron, it will become a cation with a 1+ charge
Explanation:
In a photoelectron spectroscopy experiment, photons with wavelength 130 nm cause the ejection of 6 s electrons from gold, but photons with wavelength 200 nm do not. A student claims this is because the photons with wavelength 200 nm are lower in energy than photons with wavelength 130 nm . Do you agree or disagree with the student's claim? Justify your answer in terms of the energies of the photons.
Answer:
See explanation
Explanation:
The energy of a photon refers to the energy carried by each photon. The energy of a photon is inversely related to its wavelength.
This simply means that the longer the wavelength of a photon, the lower the energy of the photon.
200nm is longer than 130nm, therefore, 130nm photon has more energy than 200nm photon.
This explains the fact that photons with wavelength 130 nm cause the ejection of 6 s electrons from gold, but photons with wavelength 200 nm do not.
La densidad del aire contenida en una habitación es 0.0013 g/cm3. si las dimensiones de la habitación son 4m de ancho, 5m de largo y 2.5m de alto, ¿ que nada tiene el aire contenido?
Answer:
La masa del aire contenido en la habitacion es 65000 gramos.
Explanation:
La densidad se define como la propiedad que tiene la materia, ya sean sólidos, líquidos o gases, para comprimirse en un espacio determinado. En otras palabras, la densidad es una magnitud que permite medir la cantidad de masa que hay en determinado volumen de una sustancia. Entonces, la expresión para el cálculo de la densidad es el cociente entre la masa de un cuerpo y el volumen que ocupa:
[tex]d=\frac{m}{V}[/tex]
En este caso:
d= 0,0013 [tex]\frac{g}{cm^{3} }[/tex]m=?V= 4 m*5 m*2,5 m= 50 m³= 50.000.000 cm³ (siendo 1 m³=1.000.000 cm³)Reemplazando:
[tex]0,0013\frac{g}{cm^{3} }=\frac{m}{50000000 cm^{3} }[/tex]
Resolviendo obtienes:
m= 0,0013 [tex]\frac{g}{cm^{3} }[/tex] * 50.000.000 cm³
m=65000 g
La masa del aire contenido en la habitacion es 65000 gramos.

Prove this reaction is a redox reaction
3 Mg + 2 FeCl3 +2 Fe + 3 MgCl2
Your answer should include the half equations
Answer:
because Redox means two words:reduction and oxidation
reduction is when oxygen is taken from a substance while oxidation is the addition of oxygen to a substance..Magnesium displaces chlorine from iron(fe)because it is more reactive than iron
and iron gives chlorine to magnesium because it's less reactive.This is due to their position on reactivity series.
Explanation:
This is called displacement reaction where by A most reactive metal remove a substance from a less reactive metal and form up a salt
and in this case the salt formed in the reaction is 3MgCl

How much heat is released when 1.4 mol of hydrogen fluoride are produced? H2(g) +F2(g) → 2HF(g) +536kJ (Please show work)
Answer:
375.2 kJ
Explanation:
H₂(g) +F₂(g) → 2HF(g) +536kJThe information the equation above provides lets us know that when 2 mol of hydrogen fluoride (HF) are produced, 536 kJ of energy (as heat) is produced.
We can then state a rule of three:
2 mol HF -------- 536 kJ1.4 mol HF --------- XAnd solve for X:
X = 1.4 mol * 536 kJ / 2 molX = 375.2 kJ_N2+_F2→ _NF3
